Rapid pop. growth in LDC’s (due to medicine and tech)puts a strain on these countries.
Population is outstripping a variety of resources, not just food
ie- oil, fresh water, arable land
Humans are able to adapt (possibilism) and create new sources of food
GMO’s, commercial farming
Larger population = more workers/ ideas (Ester Boserup)
We have the resources, but they aren’t equally shared (Marx/Engels)

9. Lowering the NIR How do we get NIR down? Two options
1. Lower Birth Rates
2. Raise Death Rates
Let’s go with option #1, because nobody likes dying.

10. How do we lower birth rates?
Empower Women
Contraceptives
More $$$ spent on education
Women attend school/ college
Become employed, work more, make fewer babies
Better education about reproductive health
Economic development/ education is a long term solution….what about the short term?
Distribute contraceptives widely and cheaply.
Less than 25% in SS Africa
Over 65% in Asia/LA
Some oppose birth control methods, primarily due to religious reasons.
